Definitions

  • an ULTIMA X Calibrator or an ULTIMA X Controller is available for use with the ULTIMA XIR Gas Monitor. Those units are hand-held, battery-powered units, that allow one person, non-intrusive calibration of the ULTIMA XIR Gas Monitor without opening the monitor or sensor housings.
  • Use of the ULTIMA X Calibrator and Controller is described in the ULTIMA/ULTIMA X Series Controller and Calibrator Instruction Manual, available from Mine Safety Appliances Company, Instrument Division, the disclosure of which is incorporated herein by reference.
  • one or more sample or calibration gases having a known concentration of analyte gas (or a simulant gas) are preferably applied directly to the sensor.
  • the present invention provides a method of communicating information from a sensor.
  • the sensor includes a source of energy within a housing thereof. Energy from the energy source interacts with an analyte in a detectable manner.
  • the sensor further has at least one transmissive section in the housing through which energy can be transmitted.
  • the method includes the step of modulating the emission of energy from the energy source in a manner that corresponds to information to be transmitted from the sensor through the transmissive section.
  • modulation refers to any change in the emission of the energy source so as to transmit information. In that regard, for example, one or more of the frequency, duty cycle, intensity etc. of the energy source can be altered or changed in a manner so as to transmit information.
  • the present invention also provides an infrared sensor system, including an infrared sensor as described above and a calibration cap adapted to be place in operative connection with the sensor housing.
  • the calibration cap includes at least one activator adapted to affect the switch in a wireless manner to place the sensor in the calibration mode.
  • the calibration cap can further include a communication detector sensitive to energy communicated through the window by the infrared energy source.
  • the calibration cap can also include a display in communicative connection with the communication detector to display information transmitted via the infrared energy source.
  • calibration mechanism 100 can, for example, be formed as a cap or partial enclosure that is placed over or around sensor 200 so as to be in operative connection with sensor 200 as illustrated, for example, in Figures 4C and 4D.
  • calibration cap 100 is formed as two connectible sections 110a and 110b which can, for example, be fabricated from a polymeric material such as polycarbonate.
  • detectors 236a and 236b (not shown in the cross- section of Figure 3B as it is out of the plane of the cross-section) which are in optical connection with chamber or volume 240.
  • infrared energy source 230 and detectors 236a and 236b are securely seated in a seating block or optical block 238.
  • Detectors 236a and 236b convert the infrared energy into electrical signals.
  • Each of detectors 232a and 232b is sensitive to a different range of wavelengths in the infrared portion of the spectrum.
  • FIG. 4A illustrates sensor 200 with a protective or environmental cap 300 positioned for attachment thereto, while 4B illustrates sensor 200 and environmental cap 300 in a connected state.
  • Environmental cap 300 includes ports 310 through which gas from the surrounding environment can pass into volume 240 while sensor 200 is in the sensing mode. Ports 310 preferably do not provide a direct or straight path for diffusion of gas into volume 240 so that the pressure/force changes associated with wind are not transmitted through ports 310 into volume 240.
  • external ports 310 are out of alignment with internal ports 320, with which external ports 310 are in fluid connection.
  • Environmental cap 300 also preferably prevents other environmental elements such as snow and rain from passing into volume 240 while sensor 200 is in the sensing mode.
  • switch 220a and 220b can, for example, cause blockage or interruption of the energy emanating from infrared energy source 230 in a predetermined manner (distinguishable from a failure of infrared energy source 230) such that the detectors of PCB 250 recognize entry of the calibration mode.
  • infrared energy source 230 operates to calibrate sensor 200 as well as to communicate information regarding the calibration of sensor 200 through a transmissive window 250 (see Figure 3B).
